application led January 3l, 1918.

T 0 all whom 'may concern.'

Be it known that l, WILLIAM TW. Bnown, a citizen ot the United States, residing at Burlington, in. the county of ilarnance and State of North Carolina, have invent-ed a new and useful Deniountable Rim, of which the following is a specilication.

rllhe device forming the subject matter of this application is a demonntab-le rim, nd the invention aims to provide novel means for operating and controlling the relatively movable ends of the rim.

lt is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

lilith the above and other objects in view which will appear as the description proceeds, the invention. resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, itbeing understood that changes in tbe precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit ot the invention,

ln the accompanying drawings Figure l shows in longitudinal section, a portion of a rim embodying the present in vention, the rim being in closed position;

Fig; 2 is asimilar view, wherein the rim is shown in an open position;

Fig.. 3 is a bottoni plan, showing a portion ot the rim; and

Fig. d is ,a cross section, taken approximately on the line fl-ft oi Fig. 3.

ln tbe drawings, there is shown a portion of a wheel rim embodying relatively movable ends l and 2 which meet at a bevel as shown at 3, Vlhe end l of the rim is pro vided with projections fi, between which is received the reduced end 5 of a lever 6, the part 5 of the lever being pivoted to the projections 1l, as indicated at 7. The opposite extremity of the lever 6 is beveled as shown at 8. A retainer or block 9 is attached by securing elements l() to the end 2 of the rim and has a beveled end ll, coacting with tbe beveled portion 8 of the lever 6, and delin` ing a recess l2, into which a tool (not sliown) may be inserted, for the purpose of prying1 the lever 6 out of the closed position shown in Fig.. l. 'lhe numeral le denotes a pair of linksa The links are in the form of bars, and are pivoted as indicated at l5 to the side portions of the retain r or block Patented Angl. 2G,

Serial No. {l/533.

9. As marked by the reference character 1G, the links are pivoted to the lever 6, intermediate to the ends ot' the lever. lWhen the lever 6 is in a closed position, the lever lies between the links 14, and presents, together with the links, a liat surface. rl latch 17, which may be a screw, is journaled for rotation in the end l of the rim. A. portion ot the head ofthe screw is out away, as shown at 18, to form a projection 19. lllien the lever 6 is swung to an open position, as shown in Fig. 2, thereby to contract the rim, tlie screw or latch 1'? may be rotated, so that the projection 19 coperates with the beveled end 8 of the lever.

The structure is simple in construction and includes but few parts, there being es sentially no elements about the device which are likely to get out of order. The conv` struction is such that severe usage may be withstood. The lever 6 folds between tlie links letand the inner curve of the rim is encumbered to a minimum extent. lt is possible, however, by inserting-a tool of any kind into the recess 1Q, to start the lever 6 toward open position. The beveled part 8 of the lever exercises a double function, in that it coacts witli the projection i9 on the latch 17, and cooperates, also, with the beveled end l1 of the retainer or block 9, to forni a recess l2, into which a tool may be inserted, as hereinbefore stated.

Having thus described the invention, what is claimed is:

l. A wheel rim embodying relatively movable ends; links each pivoted at one extremity to one end of the rim and adapted to lie against the inner curve of the rim, said end of the rim being continuous between the links; a lever pivoted at one terminal to the other end of the rim; and means for pivotally connecting the other extremity of each link to the lever intermediate the ter minals of the lever, the lever extending between the links, the distance between said means and the other terminal of the lever being less than the distance between said means and the pivoted extremities of the links, whereby said other terminal of the lever may be housed completely between the links.

2. A wheel rim embodying relatively movable ends; a retainer on one of said ends; a

lever pivoted at one terminal to the'other of said ends, the opposite terminal of the lever being spaced from the retainer to form wit
